If you intend to go pc-fair just bring along your tablet or your smartphone, surf to http://support.lenovo.com/en_MY/product-se...us/default.page , key-in the serial number and it will show u the location, warranty expiration date, model of the unit you intend to buy.. That should give you some peace of mind. Don't wait till you have purchased the unit then to realise you can't find the serial in that website..is too late obviously.
